1. Tachometer

   A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes from Greek τάχος (táchos "speed") and μέτρον (métron "measure"). Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine revolutions and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two.

1. tachometer

   A tachometer is a device used to measure the rotational speed of a mechanical component such as the engine shaft in a car. This measurement is usually displayed in revolutions per minute (RPM). Tachometers are commonly found in automobiles and airplanes to monitor the engine's RPM and ensure optimal performance.

1. Tachometernoun

   an instrument for measuring the velocity, or indicating changes in the velocity, of a moving body or substance

2. Tachometernoun

   an instrument for measuring the velocity of running water in a river or canal, consisting of a wheel with inclined vanes, which is turned by the current. The rotations of the wheel are recorded by clockwork

3. Tachometernoun

   an instrument for showing at any moment the speed of a revolving shaft, consisting of a delicate revolving conical pendulum which is driven by the shaft, and the action of which by change of speed moves a pointer which indicates the speed on a graduated dial

4. Tachometernoun

   an instrument for measuring the velocity of the blood; a haematachometer
